CAMPHOIR HOLDER FOR PIANOS.

Application filed March 7, 1916, Serial No. 32,698.

To all whom it may concern.

Be it known that 1, JOHN DE CAnLo, a citizen of the United States,residing at Brooklyn, in the county of Kings, State of New York, haveinvented certain new and useful Improvements in Camphor Holders forPianos; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will en,-

able others skilled in the art to which it appertains to make and usethe same.

The present invention is directed to improvements in camphor holders forpianos, and has for its object to so construct a device of thischaracter that the same can be easily and quickly attached to thebackboard of an upright piano, and when in place the fumes from thecamphor will protect the felt from moths.

A further object of the invention is to provide a holder of thischaracter so constructed that the camphor can be readily removed afterlosing its strength and a new piece substituted.

It has been the usual practice to drop a number of moth balls into thepiano case, but this is objectionable, since it frequently occurs thatthe moth balls will become lodged under the keys or between the wires,thus affecting the operation of the piano.

Other means have been resorted to such as suspending a bag within thepiano case filled with moth balls or camphor, but this is alsoobjectionable since mice will gnaw the bag, thus permitting the contentsto drop and affect the operation of the piano.

With these and other objects in view, this invention resides in thenovel features of construction, formation, combination and arrangementof parts to be hereinafter more fully described, claimed and illustratedin the accompanying drawing, 1n Wl11Cll1- Figure 1 is a fragmentary Viewof a back- Specification of Letters Patent.

board of a piano, showing the holder in place.

Figure 2 is a sectional view on line 2-2 of Figure 1.

Referring to the drawing 1 indicates the backboard of an upright piano,and 2 one of the tuning pins and to which the holder 3 is adapted to beattached so as to suspend the same properly within the piano case.

The holder 3 consists of a casing pref erably rectangular in shape andhas its sides t and front 5 provided with a plurality, of perforations6, whereby the fumes from the camphor block 7 may escape so as topermeate the felt to prevent ravage thereof by moths- The holder 3 isprovided with a top 8 which can be readily removed when it is desired toplace in the holder a new block of camphor.

To the back 9 of the holder is connected a horizontally disposed tube 10which is adapted to engage one of the tuning pins 2 so as to properlyhold the device in place.

The tube 10 is split, as at 11, whereby the same will expand when forcedover the pin i and frictionally grip the same, thereby holding thedevice firmly in place.

lVhat is claimed is A camphor holder for pianos comprising a perforatedcontainer, and a metal tube projecting rigidly from its back and splitwhereby it'is adapted to frictionally engage over a tuning .pin, thecontainer being of such shape as to be held thereby continuously outofcontact with other parts of the piano.

In testimony whereof, I aflix my signature, in the presence of twowitnesses.
